Tungsten Target

What is Tungsten target?

Tungsten target are components of the thin-film transistors used in TFT-LCD screens. They are used wherever large screen formats, particularly high image definition and optimized contrasts are needed. But tungsten is also used as a diffusion barrier and a conductive connector in the microelectronics industry.

At high temperatures, thin films made of materials with low melting points may diffuse and intermix with the adjacent layers. This does not happen with tungsten. This material has the highest melting point of all metals – as a result, tungsten layers are particularly stable.

Application

Tungsten target is mainly used in plasma sputtering industry.With the electric field, electron collided with the argon atom when fly to the substrate, then argon atoms and electrics were ionized .The electrics fly to the substrate while argon atoms accelerate to bomb the target, the neutral atoms (or molecules) in the target deposit on the substrate and become the coating.

Since the tungsten resistant to high temperature and corrosion, tungsten targets are widely used in petroleum chemical industry, aviation, machine manufacturing, and electronics semiconductor industries and so on.
